Specification of Letters Patent.

Patented Sept. 12, 1916.

Application filed March 11, 1913, Serial No. 753,560. Renewed Ju1y 19 1916. Serial No. 110,259.

To all whom it may concern Be it known that I, SELDEN S. GORDON, a citizen of the United States, residing at Halesite, Long Island, in the county of Suffolk, State of New York, have in vented certain new and useful Improvements in Hammers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it apportains to make and use the same.

This invention relates to hammers.

The object of the invention resides in the provision of a hammer in which the outer faces of the poll and claw are disposed throughout in a continuous curve whereby a continuously shifting fulcrum is obtained in the extraction of a nail, said extraction being instituted with a long leverage resulting in slow extraction and said leverage constantly decreasing during extraction whereby the rapidity of the extraction is constantly increased.

With the above and other objects in view the invention consists in the details of construction and in the arrangement and combination of parts to be hereinafter more fully described and particularly pointed out in the appended claims.

In describing the invention in detail reference will be had to the accompanying drawings wherein like characters of reference denote corresponding parts in the several views, and in which- Figure 1 is a side elevation of a hammer constructed in accordance with the invention, same being shown in the relation it would occupy to a nail when the extraction of the latter is instituted. Fig. 2 a view similar to Fig. 1 showing the hammer in the relation it would occupy'to a nail when the extraction of the latter has been substantially completed. Fig. 3 a section on the line 3-3 of Fig. 2, and Fig. 4 a section on the line 4% of Fig. 3. V

Referring to the drawings the hammer is shown as comprising a head A and a handle B. This head A includes a poll 10 and a claw 11 and is provided centrally with a handle receiving passage 12. The side walls of the passage 12 converge toward each other from each end inwardly so as to produce substantially opposed wedges 13 and 14 which serve to hold the head against disengagement from the handle B, it being obvious that when the handle is driven into the passage 12 it will be forced by the points of the wedges 13 and 141 and that portion of the handle which passes the points of said wedges will expand and lock the head and handle together.

In order that the full extraction of a nail may be accomplished without employing the free end of the poll 10 as a fulcrum the claw 11 is made relatively long and the outer face of both the claws 11 and the poll 10 are disposed in the same curves throughout the entire length of the claw and poll. By this construction it will be apparent that the the outer face of the poll and obviate the shifting fulcrum can travel gradually down extreme jump in the positions of the fulcrums which occurs during the final extract ing operation when the outer face of the poll is not a continuation of the curve of the outer face of the claw and serves to enable the complete extraction of the nail without excessive bending thereof. It will be noted that the curve of the outer face of the claw 11 constantly approaches the handle B. This construction brings the free end of the claw into substantial parallelism with the handle B so that when the hammer is operated to extract a nail the said handle will be at first disposed substantially parallel to the work so that an upward pull on the handle will effect the extraction. This results in the advantage of effecting extraction with a relative short upward pull rather than a relatively long sidewise and partly downward pull. Another advantage of this construction is that greater lifting power will be gained or the same amount of power will do the work better.

What I claim is 1. A hammer comprising a head, a poll, and a claw, the outer face of the head, poll and claw being disposed in a continuous curve from the end of the claw to the end of the poll and the longitudinal axis of the head disposed at right angles to a tangent to a portion of the curve included between the ends of the face.

2. A hammer comprising a head, a poll, and a claw, the outer face of the head, poll and claw being disposed in a continuous curve from the end of the claW to the end In testimony whereof, I affix my signaof the poll and the longitudinal aXis of the tnre, in the presence of two Witnesses. head disposed at right angles to a tangent to a portion'of the curve included between the SELDEN GORDON ends of the face, the inner face of the claw WVitnesses: being out of parallelism With the inner face H. L; R001),

of the poll and above the latter. 7 C. P. HARRIS.

It is hereby certified that in Letters Patent No. 1,197,929, granted September 12,

1916, upon the application of Selden S. Gordon, of Helesite, New York, for an improvement in Hammers/i an error appears in the printed specification requiring correction as follows Page 1, transpose lines 70 and 71; and that the said Letters Patent should be read With this correction therein that the same may conform to the record of the case in the Patent Oflice.

Signed and sealed this 24th day of October, A. D., 1916.
